From publisher blurb:
Liber Ingenium is a collection of 49 additional abilities for your Pathfinder Character. The base abilities of strength, Intelligence, Wisdom, Dexterity, Constitution and Charisma have been expanded to include up to 49 additional abilities that can be acquired in a number of different ways.
These additional abilities and sub-abilities allow your to more accurately and completely flesh out your character and construct a more accurate protrayal of just who your character really is.
Liber Ingenium is the first of a three book volume that provides a depth of character development not previously possible. Each ability is individually selectable, as not all need apply to your character. Each one will serve to enhance and focus your character, and provide additional dimesion.
Designed specifically for Pathfinder, LIber Ingenum is easily adapted to AD&D or any fantasy RPG.
